Abstract

A wedge toothbrush head of the utility model relates to a tool for daily hygiene and health care of oral cavity, which can go deep into the rear part of the oral cavity and solves the problem that the stenotic rear part of the vestibule of the oral cavity leads to non-thorough cleanness of rear teeth. The utility model is characterized in that the height of the head end of the toothbrush head is 11-14 mm and the height of the tail end of the toothbrush head is 16-17 mm, on the basis that the width of the head end of the toothbrush head is 7-8 mm, the width of the center part of the toothbrush head is 10-14 mm, the width of the tail end of the toothbrush head is 9-11 mm, and the juncture of the toothbrush head and a toothbrush handle is at an angle of 150-180 DEG. The detailed structure characteristic of the utility model is as the attached drawing.

Description

The mesiodens brush

The utility model is the instrument that is applied to daily oral health care.

Daily oral health care main tool is a toothbrush." the 333 " principle of brushing teeth is very important, i.e. " every day three times, three minutes after meal within, each three minutes ".Adhere to correct tooth-brushing habit, select the high toothbrush of cleaning efficiency, the generation of control bacterial plaque can be played caries prevention, periodontal disease and gum function of health care.At present people have generally recognized the importance of oral health care, and begin to note to select the toothbrush that is suitable for.Because the vestibule of mouth diease is narrower in the backteeth district, and mouth opens slightly during cleaning teeth, causes the cheek muscular tone, and the space between dental arch and the buccal mucosa is more narrow, and ordinary toothbrush is difficult to clean grinding one's teeth in sleep of rear portion, oral cavity, and this just causes the good of dental caries disease and periodontosis to send out.

For addressing this problem, a kind of tip toothbrush (the brush head end is narrower, and body is wide slightly) has appearred, can adapt to the height deficiency of vestibule of mouth diease rear portion between up and down at the bottom of the gum buccal groove preferably, the brush of more original width unanimity can clean backteeth better.But, also there is a problem, be exactly that vestibule of mouth diease rear portion is narrow, except the narrow and small problem of spacing at the bottom of the gum buccal groove up and down, also exist between dental arch buccal surface and the buccal mucosa the not enough problem of distance, current toothbrushes head end tail end height unanimity can not solve the cleaning problems of backteeth well.

The purpose of this utility model be to provide a kind of on the basis of tip toothbrush improved dental hygiene article in addition, it can clean backteeth effectively, comprises the distal surface that last is ground one's teeth in sleep.

The purpose of this utility model is achieved in that making toothbrush head end height is 11～14mm, and the tail end height is 16～17mm, and makes brush and brush holder junction form 150 °～180 ° angles.Its specific structural features has five kinds:

(1) bristle facies posterior hepatis head end thickness is 3～4mm, and tail end thickness is 5～6mm, and the head end tail end divides a word with a hyphen at the end of a line the slow camber line of circle; Bristle head end tail end length unanimity is 8～11mm.

(2) the head end bristle lengths is 6～9mm, and the tail end bristle lengths is 8～11mm, and bristle tips is divided a word with a hyphen at the end of a line into oblique line; Bristle facies posterior hepatis consistency of thickness is 5～6mm.

(3) the head end bristle lengths is 6～9mm, and the middle part bristle is the shortest, is 5～8mm, and the tail end bristle lengths is 8～11mm, and bristle tips is divided a word with a hyphen at the end of a line into camber line; Bristle facies posterior hepatis consistency of thickness is 5～6mm.

(4) bristle facies posterior hepatis head end thickness is 3～4mm, and tail end thickness is 5～6mm, and the head end tail end divides a word with a hyphen at the end of a line the slow camber line of circle; The head end bristle lengths is 7～11mm, and the tail end bristle lengths is 11～12mm, and bristle tips is divided a word with a hyphen at the end of a line into oblique line.

(5) bristle facies posterior hepatis head end thickness is 3～4mm, and tail end thickness is 5～6mm, and the head end tail end divides a word with a hyphen at the end of a line the slow camber line of circle; The head end bristle lengths is 7～11mm, and the middle part bristle is the shortest, is 6～10mm, and the tail end bristle lengths is 11～12mm, and bristle tips is divided a word with a hyphen at the end of a line into camber line.

The utility model designs and produces simply, can use existing equipment and make; Because toothbrush head end width height all has and reduces, and can go deep into narrow vestibule of mouth diease rear portion more, fully contacts with backteeth, thereby reaches good cleaning effect.
